3-5
A post office is a good example of a real-world environment in which numbers of different types can be found. Whole numbers and fractions are introduced. Numbers that occur in a greater variety of measurement situations can also be introduced. At this level, students should be encouraged to elaborate on the way numbers are used.
Pre-K-2
A toy-shop theme is used to help stimulate and generate discussion about numbers. Students use examples from a toy-shop to identify real-world uses of numbers and to write stories about those numbers.
3-5
Students investigate the ways shapes can be divided into equal pieces
with one or two cuts. The lesson provides a review of the following vocabulary
terms:
square, triangle, and rectangle; congruent, one-half, and one-fourth.
The other lessons in this unit build on this introductory lesson.
Pre-K-2
Students learn the names of solid geometric shapes and explore their properties. At various centers, they use physical models of simple solid shapes, including cubes, cones, spheres, rectangular prisms, and triangular prisms.
Pre-K-2
This lesson initiates the development of skills in collecting and recording data. Students collect data about a partner's face and tally the data from the whole class. They learn the convention for displaying a set of five using tally marks. Then students create a pictograph and pose and answer questions about the data set.
6-8
Deal with data to complete an organized chart, and create and interpret graphs to generalize a rule.

various real-world applications of different forms of measurement, including
time and distance.9-12
In this lesson, students are introduced to basic graph theory and Euler circuits. They stitch paths and circuits to create their own graphs. Students also problem solve as they design a route that creates the same pattern on the front and back of a canvas.
